. SYSTEI OF ROLLING SURGICAL ADHESIVE PLAS'IER.

Application filed September 8, 1826. Serial No. 133,897.

Adhesive plaster for hospital use is usually put up in five yard lengths, twelve inches wide, in roll form with an intervening face cloth to prevent promiscuous stick- 6 ing and to facilitate the unwinding of the plaster in service. It has been proposed to divide the face cloth longitudinally to simplify the separation of the plaster'and this is sometimes practiced. But this practice suffers the disadvantage that the face cloth,

during the winding 0 eration, has a' tendenc to pucker or huckle' transversely, whic obviously retards even winding.

The object of my invention is to provide 16 for covering adhesive plaster in suchvway as to obviate the objections and disadvantages of the old practice and in such way as to provide for the ready separation of the plaster.

The nature, characteristic features and sco e of the invention more readily will be un erstood from the following description taken in connection with the accompanying drawing forming a part hereof, wherein Figure 1 is a perspective'view of a roll of laster embodying my improvements.

ig. 2 is a sectional view.

According to my invention, adhesive plaster 5 is rolled with an intervening cover or facing strip, consisting of longitudinal sections 6 having their proximate ed es 7 in overlappin relation and one or bot turned or longitu inally folded as at 8. In further accordance with my inventive thought,

as the outer or remote edges of the facing sections are turned or inwardl folded as at 9. The effect of this is to esta lish distance or s acing elements substantially the same as t e medial spacing elements or lapped edges of the facin sectionand the net result is uniform rol mg of the plaster and facing sections, the latter being maintained in parallelism. Under the provision stated, puck- .chase gins.

facing cloths in rolled adhesive plaster,

which consists in inwardly turning the mar- 3. The method of reventing puckering of facing cloths in ro led adhesive plaster,

-which consists in providing se arate strips having proximate edges in over apping relation and having remote edges turned to sub- 05 stantially coincide with the thickness of the overlalp.

4. e method of preventing puckering of facing cloths in rolled adhesive plaster, which consists in providing cloth sections 10 whereof the proximate edges are in overlapping relation and at least one of them turned, and turning the outer mar of the cloth sections so that the will su stantially coincide in thickness with the overlapped margins.

5. A roll of adhesive plaster having a facing cloth, consisting of crinoline sections having their proximate edges in overlapping relation throughout the roll and having their remote e s inwardly folded to substantially coinci 9 with the thickness of the la ed edges. 7

n testimony whereof I afix my signature.
